Title: Syringe esp. for injecting anaesthetic into the lower jaw - includes pref. triangular needle guide and scale showing depth of needle penetration
IPC: A61M5/32
Filed: 1977-11-15
Abstract: Syringe, more partic. for penetrating a hard wall as when injecting an anaesthetic into the lower jaw, has a triangular mouthpiece guide through which the needle can slide. The body of the syringe has a scale which indicates the length of the needle projecting through the tip of the guide.

Title: Pole wheel construction for vehicle dynamo - has disc section with annular protrusion on one surface, as well as star shaped extensions, all coupled by axial bore
Inventor: MURAKAMI KINSHIRO
IPC: H02K15/02
Filed: 1978-03-31
Abstract: The rotor for a claw pole type dynamo consists of two identical and interleaving sections. Each section is produced from a cylindrical steel blank by press forming in stages.
